# Binary number (`binary_number`)

> **Draft.** Draft records have not been reviewed yet and may be incomplete or wrong; do not treat them as authoritative for legal or compliance decisions.

Non-negative integer written in base 2 with the digits 0 and 1, with or without the prefix 0b that programming languages use. A decimal number made of zeros and ones also matches when the prefix is missing, so use the field name or context.

- Pattern of: `numeric`
- Personal data (PII): no
- Categories: All measurable values (percentage, amount and e.t.c) (values), Common (common)
- Countries: global
- Languages: Common to most languages (common)

## Detection

Regular expression (Python `re`):

```
^(?:0[bB])?[01]+$
```

## Examples

- `0b1011` — 11 with the prefix
- `101010` — 42 without the prefix
- `1021` (invalid example) — The digit 2
